It’s not much of a stretch to say that Earth’s inner structure, especially the innermost spherical core, has stupefied ...

The Earth's inner core was once liquid, but has turned solid over time. As the Earth gradually cools, the inner core expands outwards at the surrounding iron-rich liquid "freezes." That said, it ...

Iron is one of the main elements found in the Earth's inner core, which is characterized by extremely high temperatures and pressures. Determining how iron behaves in these extreme conditions ...

Physicists suggest a new explanation for the interesting properties of the Earth's inner core. Credit: NASA / Getty Images According to a new "holy grail" scientific discovery, the blazing-hot ...

The inner core of Earth may have changed shape in the past 20 years, according to a group of scientists. The inner core is usually thought to be shaped like a ball, but its edges may actually have ...

Scientists have uncovered new information about the Earth's core: it may not be completely solid. Instead, its center may be more malleable than expected and has changed shape in recent years.

New research sheds light on the Earth's "innermost inner core," offering new insight into the formation of the planet and its magnetic field. From our morning news briefing to a weekly Good News ...

The Earth's internal layers including the mantle, outer core and inner core. New research shows the inner core undergoes structural transformation likely caused by outer core disturbance.

Scientists have discovered that Earth's inner core, previously thought to be solid and unchanging, has experienced significant shape changes over the past 20 years. Through advanced seismic ...

Seismic wave data previously suggested the Earth’s hot inner core is slowing its spin. Now, researchers say it’s also deforming around the edges Sara Hashemi Scientists released an update to a ...
